The reality star, who was hawking her new memoir, Give Them Lala, rocked a silver sparkly mini dress with a pair of tan heels.
Lala did not put on her engagement ring which is worth an estimated $150,000. Inside the event, one fan asked how she was holding up following the news of her split. "I’m doing what I can," she revealed.
Later, Lala said she was a "smart bitch" and would get back on her feet in no time. The public appearance is her first since the drama started with Randall over the weekend.
As RadarOnline.com previously reported, on Saturday, photos emerged on social media which allegedly showed the B-list film producer hanging out with two unidentified women in Nashville in a hotel lobby.
The photos appeared to infuriate Lala who decided to pack up her things and leave their home. She was spotted checking in at a Beverly Hills hotel to get away from her fiancé.
Sources close to Randall claim the relationship is being worked on and Lala is coming back home. An insider in her camp scoffed at the claims saying Lala was over it.
A source told Page Six, "Randall always lives a double life. He lives the life of a husband or boyfriend, and then he lives the life of a serial partier and then goes on a bender.”
As we first reported, Lala's decision to leave comes as Randall is facing serious financial issues. In court documents obtained by RadarOnline.com, the producer revealed in his custody battle he is drowning in debt.
He is currently on monthly payment plans with the IRS and American Express. Randall owes Uncle Sam around $500k and another $393k to American Express. He is also currently being sued for $281k over unpaid rent on office space.
